Could somebody send me a Maplet to solve systems of equations of any range ( linear,exponential , logarithm My e-mail is : javi36@ono.com

There is one thing which, as far as I know (please correct me if I'm wrong), you can do with other languages like FORM and MATHEMATICA, but cannot do with MAPLE. That is, to use patterns in replacement rules. If this were included in a future version of MAPLE, I wouldn't use MATHEMATICA ever again! For example, in MATHEMATICA you can write the following input: f[{a,b}] + f[c] /. f[{x_,y_}] -> p[x+y] and then you get the following output: f[c]+p[a+b] Another example, {1,x,x^2,x^3} /. x^n_ -> r[n] then you get {1,x,r[2],r[3]} The underscores are used to mean "any expression". For example, x_ means any expression to be named x. MATHEMATICA also has things like x__ (x with two underscores), which means any sequence to be named x, and x___ (three underscores) which means any sequence of zero or more expressions to be named x.

Here are the steps for making StartMaple example with Dev-C++.

1. Start Dev-C++.
2. Click File - New - Project, select Console Application, check C Project radio button and type the name of the project - something like SMexample.
3. Copy the source from ?StartMaple help page and paste it in main.c (instead of pretyped text there).
4. Click Alt+P (or Project - Project Options), go to Directories, select Include Directories and add C:\Program Files\Maple 10\extern\include there.
5. In Parameters (in Project Options) in the Compiler window type -D_MSC_VER and in the Linker window click Add Library or Object and add "../Program Files/Maple 10/bin.win/maplec.lib" .

I'm just curious - and I don't work for Maplesoft :) - but what do people here actually use Maple for ? What sorts of problems are you tackling, and what commands/packages do you typically use ? I'm also interested to hear about how people use Maple in teaching (for those that do). Myself I use Maple for research in computer algebra - mostly topics related to polynomial systems. For example, I may be trying to find algorithms to compute in new domains. I like Maple because it is very easy to program mathematical algorithms. It is not quite so easy to get them to run fast, but that gives me something to work on :) I mostly use my own software (PolynomialIdeals + recent code), but I also use the Groebner package and now the RegularChains package (new in Maple 10). I make a point of trying all the other packages every once in a while, since you never know when something is going to be useful. I use the plot commands a lot as well.

I am trying to calculate deflections of a beam (under their own weight) on multiple supports with a (nonsymmetric) overhang on either end. I've done the calculations by hand but would really like to write something in Maple to do it as I have alot of configurations to calculate. Can anyone help or give me some suggests? The way I have calculated the deflections involves calculating the reaction forces on the beam. Then calculating at general points along the beam. Integrating to give the bending moment M. Setting boundary conditions (such as M=0 at ends,M=M at supports etc). Then the deflection of the beam is given by y=(W/IE)*int(int(M)) subject to boundary conditions (y=0 at supports y'=y' at supports) where W=Load per unit mass, I=second moment of area E=Young's Modulus.

Dr. Sarah J. Greenwald, Appalachian State University, and Dr. Andrew Nestler, Santa Monica College have put together a site about mathematics and The Simpsons,including an exhaustive list of all math references on the show, relevant images, and the math background of the writers. They use this material to introduce concepts, motivate students and reduce math anxiety, apparently. Aside from its potential educational value, it's fun. See Simpson's Math. eithne

I would like to know how to tell Maple not to assume that two things commute, that is, AB != BA. I would like to be able to have maple expand expressions such as

(A+B)^2 = A^2 + AB + BA + B^2

instead of having it collect terms and ignore the multiplication order as it does when I use the "expand()" function.

Need to solve the following equation for real roots:
x^4 + 5*x^3 + 4*x = sin(x), with Digits:=6
it is giving me only one real root, but during the plot it shows two intersections suggesting two real roots. How can i overcome this problem?

I think Maple should have compression in the .mw format. I don't care if it breaks backwards compatibility, it should be an option. Later you can make it the default. I recently looked at this post, which links to an 11MB worksheet. Using "zip" compressed it down to 60KB. This is beyond bad - it's obscene! Note that this would also fix the problem of broken mail servers corrupting .mw attachments. Just swipe some FreeBSD code and put this feature in. Please!

Whenever I visit San Diego, I never miss a chance to go up to Palomar Observatory. It is the home of the legendary Hale 200 inch telescope that was the reigning champion among telescopes until about 25 years ago. It is perched atop Palomar mountain and the building is open to the public. You can see through a window, the famed instrument though you cannot actually approach it. The telescope aside, it's an amazing drive from San Diego to the mountain as it goes through some of the most scenic areas in Southern California. If you have half a day or if you're driving from San Diego to Los Angeles, it's a great way to see the country and to visit a significant site. Great picnic areas and a little gift shop as well.

What is the latest version of Maple 10 available? ( as in 10.x)

I'd like to gauge interest in an online session on authoring Maple documents using new features in Maple 10: document blocks, embedded components, tables, autoexec code, task templates, embedded assessment, 2d math, etc. Would you participate in such a (free) session? -Laurent
